Incase you were already thinking about back-to-school shopping, Mayor Bloomberg has announced a shopping event in September that will coincide with Fashion Week, called Fashion's Night Out. On September 10th, retailers in all five boroughs will stay open until 11 p.m., holding in-store events. The Mayor even has Vogue editor-in-chief Anna Wintour on his side, though she'd never shop off the rack. She said the event will help protect the city's fashion "creativity and diversity." The overall goal here isn't to make you look pretty, though, it's to support local business, promote tourism and economic activity throughout the city as part of the Administration’s Five Borough Economic Opportunity Plan. The event will also boast a special limited-edition t-shirt with proceeds from sales going to the National September 11 Memorial & Museum, and shoppers are being encouraged to donate their own clothes at participating stores for the New York City AIDS Fund.
